Finally a bottle of which is tightly ... just important for school bag or sports bag ... because who would pay books because softened or work in wet clothes Sport. Closure can be readily disassembled for cleaning. My daughter has a day to school and is excited.

We have many bottles from other manufacturers through, but all were nothing. Either bad drink from it, strange taste of water or dripping ... but this bottle seems to be really great times.
